Method Detail

bindVector

public void bindVector(ColumnMetadata schema,
                       VectorAccessor va)

Overrides:

bindVector in class BaseScalarReader.BaseVarWidthReader

valueType

public ValueType valueType()

Description copied from interface: ScalarReader

Describe the type of the value. This is a compression of the value vector type: it describes which method will return the vector value.

Returns:

the value type which indicates which get method is valid for the column

getBytes

public byte[] getBytes()

Specified by:

getBytes in interface ScalarReader

Overrides:

getBytes in class AbstractScalarReader

getDecimal

public BigDecimal getDecimal()

Specified by:

getDecimal in interface ScalarReader

Overrides:

getDecimal in class AbstractScalarReader
